Watch a Green Home Get Built in One Day

Witness the assembly of Seattle’s first LEED Platinum (targeting certification) modular home. Transported via truck from the factory in Idaho, six boxes (measuring 12′ wide, 20′ long and 16′ high) will be installed one-at-a-time by crane onto the foundation, forming this prefab demonstration home.

The three bed/2.75 bath 1,790 square-foot single-family home is the brainchild of Seattle-based Greenfab, a provider of sustainable, well-designed homes and communities with the long-term vision to encourage mainstream use of modular construction to provide healthier homes at a more affordable price point.

For a preview of how a prefabricated modular home is put together, watch this time-lapse video. Greenfab also has videos of its project’s progress at

Located on a previously undeveloped portion of a subdivided property, the Greenfab demonstration home is an example of true urban infill. The home is being built to target LEED for Homes Platinum, Built Green 5-Star+ and Energy Star certification standards. Greenfab is targeting net-zero energy and aiming to meet the goals set by the 2030 Challenge, which demands all new buildings achieve a fossil fuel reduction of 60-percent for 2010, a 100-percent reduction (carbon neutral) by 2030.

When: Tuesday, December 7th from 10 am – noon

Where: 1827 S Lane St, Seattle, WA 98144 (near Boren Ave S and Rainier Ave)

Interviews: Johnny Hartsfield and Swen Grau from Greenfab (developer)
Robert Humble from HyBrid Architecture (architect and home owner)

Benefits of Modular:

Less construction waste: Due to factory construction that allows for precise cutting and use of materials, modular is inherently green with 50 to 70% less waste generated compared to traditional site-built construction (meaning fewer materials end up in landfills).

Shorter construction time: The demonstration home will be nearly 70% complete when it arrives at the site. Factory construction occurs simultaneously with site preparation and foundation pouring, which means most modular projects are completed 30 to 50% faster than traditional construction.
